korotovsky/slack-mcp-server
The most powerful MCP Slack Server with no permission requirements, Apps support, GovSlack, DMs, Group DMs and smart history fetch logic.
This tool helps you gather information from Slack workspaces, including public channels, private conversations, and direct messages, even in large enterprise setups. You can input channel names, message dates, or keywords, and it outputs specific messages or conversation histories. It's designed for operations engineers, data analysts, or anyone who needs to extract and analyze Slack data for reporting, compliance, or archival purposes.
1,441 stars.
Use this if you need to programmatically access, search, and retrieve message history from Slack channels and direct messages, including unread messages and specific threads, without constantly refreshing tokens or needing extensive permissions.
Not ideal if your primary goal is to send a high volume of new messages to many channels, as posting is disabled by default and requires explicit configuration.
